I don't know if there's something just posted here (I've searched but nothing ...)

Anyway, I'd like to know if there's a plug to find duplicated songs in a playlist and match them.

Regards,
Piero

What do you mean "match them"?
There is function Playlist -> "remove duplicates". Maybe it is what you are looking for...

Yes WILU,
that's it.

Thanks for the reply and sorry for haven't searched better before posting ....
